Question

2x² + 3x-5=0
solve using quadratic formula

Answer 1

x1=-5/2, x2=1

Explanation:

because if you use quadratic formula

you would have x = -3 + or - √3^2 -4 x 2 x (-5)/ 2 x 2

simply and combine like terms give you

x = -3 + 7 / 4

x = -3 - 7 / 4

then you get

x = 1

x = -5/2

Answer 2

x1=-5/2, x2=1
